• Windows Forms Get the handle of each open window.

  I am in quite a predicament here. What I need to do is call some sort of API, (from User32 ) that retrieves the handle of each open window, (minimized or open) and store it in an array. I looked through the functions in User32...and am not sure how to use EnumWindows and am not sure if that will do what I want. The second part I need to know how to do is store them in an array. IntPtr[] hArray = new IntPtr[] Any help is appreciated. Ugh, translating C# into VB syntax always seems to more easily done by just rewriting it: Imports System Imports System.Collections.Generic Public Class WindowEnumerator Private Delegate Function CallBackPtr(ByVal hWnd As IntPtr, ByVal lParam As IntPtr) As Boolean Private Declare Auto Function Enu ...Show All

• SQL Server MTS

  What is microsoft transaction server and for what it is used Hello, MTS is now known as (included within actually) COM+. Amonst other things, it is able to coordinate distributed transactions within com+/MTS aware components. In the old days of MTS, you needed to code specifically for MTS, and manually enlist components into a distributed transaction, then register and host these components within an MTS server instance. Not sure what is required for COM+ nowadays, however a good Googling will soon solve that :) Cheers, Rob ...Show All

• Visual C++ Where shall I ask the quesiton about C? E.g. Question about how to generate different random numbers...

  Dear all, I had one question about generating different random numbers. One piece of my code is as follows. Actually, because of the limited time, I don't think it can work. Its principle or algorithm is only to guarantee different values between generated values border upon/nearby. However, how to guarantee the value is different with all the previous ones, not only the border upon value. void initRandom() { int i,j = 0; for (i = 0; i < 100; i++) { random_numbers = rand() % 100; // Get random number. // Try to compare the value with previous ones. for (j = i; j==0 ; j--) { if (random_numbers[j] != random_numbers[j-1]) { break; } else { random_numbers[j] = rand() % 100; } } } } Do yo ...Show All

• Visual Basic Windows Service ~ Service started successfully - NOT!

  Hi, I've developed an app as a windows service, which in the OnStart event calls an Init routine which sets up the service, check connection to dB etc, dump a log to the EventLog, and returns a True or False. If I get a False back, I execute a Me.Stop. In the event log, I see the log I dumped, then "Service stopped successfully.", then a "Service started successfully." message. It looks like these last two msgs are being output when the OnStop/OnStart events complete. How do I get my service to NOT output the "Service started successfully." msg when the Init routine fails, and instead output a "Service did NOT start successfully." or similar instead Many thanks ...Show All

• .NET Development Programmatically determine calling method at execution time?

  Without using StackFrame, how might one go about determining the method that called the current method I need this for logging but do not want to use StackFrame since it has difficulties outside of IDE environment. Looked and looked - no can find. For example, method A and B each call method C. From method C, I want to be able to log who the parent method was that called me. Thanks.

• Visual C# Process class used from Windows Service fails

  I'm having trouble with the Process class. I have a Windows Service running as SYSTEM and I want it to spawn processes on behalf of users. I get the user's password there securely and create a SecureString. I get a Win32Exception "Access Denied" on Process.Start. If I run the service under the same account as the user I want to start for, I still get the exception except it says "The handle is invalid". I've checked and checked the SecureString and I've made it read-only so I don't think that's it. I actually had gotten it to work some time ago if I impersonate the client but this isn't really practical since the job can be queued up waiting for some time. I've signed all the assemblies involved and I've given the ...Show All

• Visual Studio 2008 (Pre-release) WSE 3.0 versus WCF

  i am confused about whether i should be writing our new web services in WCF or WSE 3.0. many of our CLIENT applications still run older operating systems, such as Windows 2000. do my client applications need to be running the .NET 3.0 framework to easily communicate with a WCF web service If so this means it will only run on WinXP SP 2 and Vista right If so, should I be considering WSE 3.0 instead then Or will this be getting phased out Me confused. this post here says clients need xp sp2 or vista http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=224021&SiteID=1 "As far as client-side operating systems goes, WCF requires XPSP2 or Vista." ...Show All

• Visual C++ recv won't return on socket close

  Sorry to make my first post a cry for help but I'm running out of places to look. I have a TCP server that accepts connections and than handles the new client sock in a new thread. Everything is working fine except when the client closes ungracefully the socket stays open and my recv is still blocking instead of returning SOCKET_ERROR. I've shutdown the remote client box but my recv won't return and netstat still shows the TCP socket to be ESTABLISHED. It's not a huge deal but I'm leaving threads laying around and not realeasing my socket handles. Any ideas Thanks. Hi, my understanding of TCP is, that it tries to handle network problems gracefully. E.g. if you have a telnet connection to some o ...Show All

• Internet Explorer Development Banning from a forum?

  Hello, I would like to know how does a ban from forum works Does the server ban the ip address But doesnt the ip address always change I would appreciate any help on understanding this matter. Thanks. Sounded like you were asking about banning on these forums. It would depend on your forum.  If your forum requires login to perform an action then simply disabling a login might suffice if your login validation requires a valid email.  You could add a rule that certain IP addresses are forwarded to a "no access" page; but that would tend to ban more than one computer as the IP a web server sees is generally the gateway's IP address.  In large organizations many ...Show All

• Windows Forms using button control to navigate between textboxes

  Hello, I am designing a touchscreen app and am really struggling with the control navigation. I have 5 textboxes from top to bottom and I have a Button labelled "UP" and a button labelled "DOWN". What I am trying to do is when the user pushes the "DOWN" button the focus of the control will go the texbox below it, and the same when the "UP" button is pushed. So if the user keepes pushing "DOWN" the focus will move through the textboxes and stop at the bottom. any help appreciated. Regards Peter You more than likely have a problem keep track which control has the focus. As soon as the user clicks the button, you've lost track. T ...Show All
